Durability is an essential question for the use of geomembranes. The paper is a contribution to this question, by using, in addition to the classic tests, a molecular approach by the FfIR analytical technique (Fourier Transformation Infra Red). The tests were performed on the one hand on samples subjected to ageing processes in the laboratory, and on the other hand on samples taken from existing structures. These studies have shown good behaviour of the geomembranes when insf.?lled in normal conditions of use.
